And today's storm is not the end of the bad weather on the horizon, as yet another storm is forecast to hit the Midwest, parts of the South and the Northeast this weekend.

Because of all the snow -- and flooding forecast -- storm alerts are issued for 20 states from Wyoming down to Georgia and into New York.

Heavy snow continues to pound the Midwest from Chicago to Detroit, and is expected to move into western New York by the evening.

A multiple-vehicle pileup occurred around 11:20 a.m. on U.S. Route 23 in Fenton Township, Michigan, about 16 miles south of Flint. At least one person was killed and several seriously injured in the chain-reaction crash that involved two big rigs, police said.
